This its a badass product

Tony Graham in New Mexico – Machine this part was bought for: 2013 KAWASAKI KX250F

Comments On Apr 10, 2015:If you are looking for a great pipe for this price its a steal. the only thing is. Is that the spark arrestor is holding back all of that power and all it takes is a little allen wrench to put it on and go buy a new clamp if putting on stock header.

A Nice Upgrade Over Stock

matt in UT – Machine this part was bought for: 2013 KAWASAKI KX250F

Comments On Jan 28, 2015:Of note, this slip-on doesnâ??t use a tightening band to connect to the header pipe in the same way that the stock exhaust does. Itâ??s a matter of applying a thin layer of silicone to the pipe where it connects to the header per the instructions. The exhaust note didnâ??t change much over stock and I honestly didnâ??t notice any changes in power. The spark arrestor can easily be removed if need be without disassembling the pipe and of course it looks much nicer.

Great pipe for a great price

Sam in CO – Machine this part was bought for: 2012 KAWASAKI KX450F

Comments On Jul 22, 2014:If you've mangled your pipe in a crash, look no further. This is a great pipe at a great price. I can't say one way or another about any power increase as I've never ridden my bike with an OEM pipe, but I wouldn't hesitate to buy FMF again.
Only complaint is that the "graphics" on the pipe scratch very easily and the graphics on one side peeled completely off.

Best thing I've added to my WR450

Todd in AB – Machine this part was bought for: 2012 YAMAHA WR450F

Comments On Jun 28, 2014:Very happy with this silencer! Added noticeable power to my WR. If you aren't a fan of a little more noise you may not like it but the price is better then the Q4.

Still not that quiet, but better

Kyle in OR – Machine this part was bought for: 2012 YAMAHA WR450F

Comments On Sep 05, 2013:I bought the Core 4 and ran it for a short while, but the sound made my ears ring so I bought the quiet insert. It made it quieter, but not as quiet as I was hoping for. It's cheap though and worth the price. I the power didn't seem to change much, maybe just slightly softer on the bottom.

Additional Comments On May 28, 2014:I bought the Core 4 and ran it for a short while, but it was so loud that it made my ears ring so I bought the quiet insert. It made it quieter, but not as quiet as I was hoping for. The insert is cheap though and worth the price. The power didn't seem to change much with the quiet insert, maybe just slightly softer on the bottom but still a huge improvement over the stock pipe.
